ADOLPH OSTLUND, OF EXLINE, IOWA.

PICK-FASTENER.

Specification of Letters Patent.

Patented Apr. 2'7, 1915.

Application filed September 30, 1913. Serial No. 792,645.

To all whom it may concern Be it known that I, ADoLPH OSTLUND, a citizen of the United States, residing at EXline, in the county of Appanoose and State of Iowa, have invented certain new and useful Improvements in Pick-Fasteners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a pick fastener and has for its object the production of a simple and efficient means for holding the pick head upon the handle.

Another object of this invention is the production of a wedge which is adapted to detachably hold the pick head upon the handle for allowing the pick head to be removed when desired.

With these and other objects in View this invention consists of certain novel combinations, constructions and arrangements of parts as will. be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a side elevation of the device showing a pick head carried thereby. Fig. 2 is a sec tional view taken through the device showing the several parts assembled. 3 is a section taken on the line 33 of Fig. 2. Fig. 4 is a perspective view of a portion of the device. Fig. 5 is a perspective view of the wedge.

Referring to the accompanying drawing by numerals 1 indicates the usual sleeve which is adapted to receive the handle 2. This sleeve is provided at its outer end with an enlarged body 3 having a pocket as indicated at 41- A tongue 5 is positioned within this pocket and is retained therein by means of the pins 6. This tongue is also provided upon its outer portion with a curved side 7 and a slanting side 8. The slanting side 8 extends to form the shoulder 9 which extends evenly with the face of the body 3 as shown at 10.

A pick head 11 having a pocket 12 is positioned upon the tongue 5 so as to allow the tongue 5 to extend into the pocket 12. In order to retain this head 11 upon the tongue 5 there is provided a wedge 13 which tapers toward its inner end as indicated at 14 and is curved throughout its entire length as indicated at 15. After the head 11 has been placed upon the tongue 5 the reduced end 1-1 of the wedge 13 may be positioned within the pocket 12 formed in the head 11. By driving this wedge 13 inwardly it will ride upon the curved side 7 of the tongue 5 so as to pass through the opening 16 formed in the body 3. In this manner as the enlarged end of the wedge 13 passes into the pocket 12 and bears upon the curved side 7, the head 11 will be locked securely in engagement with the tongue 5.

It will be seen by referring to Fig. 2 that the portion of the body 3 adjacent the opening 16 is tapered toward its inner edge so as to bear upon the wedge 13 for holding the wedge within the opening 16 thereby preenting the wedge from accidentally disengaging the body and pick head. It will also be noted by referring to Fig. 2 that thehead 5 bears upon the shoulder 9 and in this manner tends to hold the several parts of the device in firmer engagement with each other.

From the foregoing description it will be seen that a simple and eflicient means has been produced for detachably holding the pick head in engagement with the retaining portion of the pick.

Having thus described the invention, what is claimed as new, is 1. In a pick of the class described, the combination of a body having a projection, said projection provided with a curved side, said body provided with an opening and with a biting edge formed adjacent said opening, a pick head positioned upon said projection, a wedge engaging said projection and passing through said pick head and the opening formed in said body, whereby said biting edge will engage said wedge, whereby the wedge will be held against accidental displacement and said pick head will be held upon said projection.

2. In a pick of the class described, the combination of a sleeve having an enlarged body formed thereon, a tongue secured within and extending from said body, said tongue provided with a slanting side and with a curved side, said body provided with an opening adjacent the curved side of said tongue, said body tapering rearwardly adjacent said opening to provide a biting edge at a spaced distance from the curved side "of said tongue, a pick head carried by said vented and thus the head Will be retained tongue, a Wedge passing through said head upon said tongue. 7

so as to engage said tongue and pass through In testimony whereof I hereunto af'fix my theopening formed in said body, whereby signature in presence of two Witnesses. said biting edge Will engage said Wedge so ADOLPH OSTLUN D. that any'outward movement of the Wedge Witnesses: will cause the edge to dig thereinto, whereby I HERMAN CARLsVORD, accidental displacement of the Wedge is pre- Gus.
